- Created MotorState as an enum describing discrete states a motor may be in
- moved ThrustCurveMotorState info back into MotorSimulation
-- MotorSimulation will be used by the simulation code.
-- tracks simulation-time info, such as event times, and current state ( <MotorState> )
- MotorConfiguration no longer have any knowledge about their simulation info
- moved functionality (BUT NOT STATE) into ThrustCurveMotor
-- can query about thrust(t), mass(t), cgx(t)
